Golf club alignment device

ABSTRACT

An alignment device for attachment to the striking face of a golf club head includes a pair of elongate guide rods, a pair of connection plates for attachment between the proximal ends of the guide rods and the striking face of the head, and an adhesive layer for mounting the connection plates to the striking face. Each guide rod includes a magnet and each connection plate is constructed of a magnetically attractive material so that the guide rods can be used during practice and removed during play.

BACKGROUND OF THE INVENTION

This invention relates generally to golfing equipment, and more particularly to a device to improve the golfer's stroke and aim when putting or otherwise driving a golf ball toward a designated target.

Prior art putters have been developed with various features to assist the golfer in properly aligning the club and the ball prior to stroking the ball toward a distant target during training and actual play. Such features have included projections integral with or removably connectable to conventional putters that extend forwardly of the striking surface or area of the putter to bracket the “sweet spot” of the putter and provide some visual alignment between the putter and the distant target. Other prior features include slots, alignment marks, and so on for enhancing alignment between the putter and the ball.

Alignment devices which extend forward of the face plate of the golf head are particularly helpful for teaching a golfer the proper position of the striking portion of the face plate with respect to the golf ball and the hole during practice or training. However, such devices are not permissible during play under current United States Golf Association (USGA) regulations. Ideally, it would be desirable to use the same putter or other golf club for both practice and play so that the reflexes and muscle memory learned with one putter during practice can be used during play without the difficulty of adapting to a different putter. Although the prior art has addressed this issue, there remains a need for quickly and effectively installing and removing alignment devices for golf clubs. In addition, there remains a need for adjusting such devices to suit a golfer's particular skill level.

BRIEF SUMMARY OF THE INVENTION

According to one aspect of the invention, an alignment device for attachment to the striking face of a golf club head includes at least one elongate guide rod and at least one connection plate for attachment between the proximal end of the guide rod and the head. The at least one guide rod is removable from the at least one connection plate.

According to a further aspect of the invention, an alignment device for attachment to the striking face of a golf club head includes a pair of elongate guide rods, a pair of connection plates for attachment between the proximal ends of the guide rods and the striking face of the head, an adhesive layer for mounting the connection plates to the striking face, and removable connection means operably associated with the connection plates and the proximal ends of the guide rods for removably connecting the guide rods to the connection plates.

According to another aspect of the invention, a putter includes a head having a striking face, a pair of connection plates attached to the striking face, and a pair of guide rods removably connected to the connection plates for receiving a golf ball therebetween.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, and to FIGS. 1-4 in particular, an alignment device 10 for golf clubs in accordance with the present invention is illustrated. The alignment device 10 can be adapted for use with a particular golf club such as a putter 12, driver, wood or the like, and is intended to help a user both align the sweet spot of the golf club striking face with the golf ball and orient the striking face of the head perpendicular to a straight line from the hole to the golf ball to thereby maximize distance and accuracy.

The alignment device 10 is shown attached to the striking face 16 of a putter head 18 on a putter 20 having a typical shaft 22 that extends from the head. Preferably, the alignment device 10 includes a pair of spaced guide rods 24 and 26 that are connected to the toe region 28 and heel region 30, respectively, of the head 18 on either side of the sweet spot 32 and above the sole 34 so as to not interfere with putter movement during use. An alignment mark 35 typically denotes the area of the sweet spot 32.

In this embodiment, the guide rods 24 and 26 are preferably of solid cylindrical construction with a diameter of about 0.25 inch and a length of about two inches. However, it will be understood that the rods 24, 26 may be hollow and/or of any shape such as conical or triangular, square, oval, or hexagonal in cross section, and so on. It will be further understood that the rods may be of any diameter or cross dimension and length. The rod 24 is preferably inserted into a bore 36 (FIG. 2) formed in the toe region 28 of the head 18. Likewise, the rod 26 is preferably inserted into a bore 38 of the heel region 30. Preferably, the bores, and thus the rods, are equidistance from the sweet spot 32, so that the golf ball may be aligned with the sweet spot during use.

The rods 24, 26 can be permanently installed in the bores through any well-known permanent connection means such as adhesive bonding, welding, press-fitting, and so on. However, the rods 24, 26 are preferably removably installed in the bores through any well-known removable connection means such as cooperating threads, double-sided adhesive tape, hook and loop fasteners, inter-engaging tabs, magnets, and so on. In accordance with one embodiment of the invention, the rods are preferably constructed of magnetically attractive material and a connection plate 37 in the form of a magnet (FIGS. 2, 4) is installed in each bore for removably connecting the rods to the putter head 18. In accordance with a further embodiment of the invention, a connection plate in the form of a thin disk of magnetically attractive material may be installed in each bore and each rod is magnetized or at least a distal end of each rod may be magnetized or include a magnet. In this manner, the rods may be installed for practice or training and readily removed for playing so as to conform with USGA regulations. Accordingly, the muscle coordination and reflexes learned with a particular golf club during training can continue to be used without the necessity of adapting to a different golf club during play.

When the guide rods 24, 26 are installed on the head 18 of the putter 20 (or other golf club), they provide an area or space 40 (FIG. 3) within which a golf ball 42 (shown in phantom line) can be received. In order to properly aim and strike the ball, the rods 24, 26 are aligned with the cup, hole or other designated target with the rods on either side of the ball. In this position, the striking face 16 is generally perpendicular with respect to an imaginary line extending between the ball and the distal target. Once the golfer is comfortable with the relative positions between the putter, golf ball and distal target, the putter is brought backward then forward in a typical swinging motion, with adequate care to ensure that the golf ball 42 is struck with the striking face 16 without contacting the rods 24, 26. If the golfer executes the putting stroke so that the golf ball is positioned either too close to the heel or toe regions, one or the other of the rods 24, 26 will strike the golf ball. The golfer is thereby provided with an unmistakable indication of a faulty putting stroke. When the putter is used for actual play, the rods are removed so that the same putter (or other golf club) can be used for both practice and actual play.

The width of the area 40 can be selected to accommodate either beginning golfers or those with intermediate or advanced skills, since a narrower area 40 requires greater maneuvering skill than a wider area. Accordingly, it is contemplated that the head 18 can have two or more pairs of bores 36, 38 (shown in phantom line in FIG. 2 for example as 36A and 38A) so that as a golfer's stroke is improved, the rods can be removed from the bores 36, 38 and placed closer together in the bores 36A, 38A.

While it is preferable to employ a pair of guide rods during use, it will be understood that a single guide rod can be used for aiming and striking the ball, especially when the golfer consistently strikes the ball too close to the heel or toe regions of the striking face.

Referring now to FIGS. 5 and 6, an alignment device 50 for golf clubs in accordance with a further embodiment of the present invention is illustrated. The alignment device 50 preferably includes a pair of spaced connection plates 56 and 58 that are connected to the toe region 28 and heel region 30, respectively, of the head 18 via an adhesive layer 60. A pair of spaced rods 52 and 54 are in turn removably connected to the connection plates 56 and 58, respectively.

The connection plates 56, 58 are preferably constructed of a thin disk of ferromagnetic sheet material, such as stainless steel or other magnetically attractive material, but may alternatively comprise a magnet or the like. Likewise, the proximal ends 62 of the guide rods 52, 54 are either magnetized or contain a magnetic insert for removable attachment of the rods to the connection plates. The relatively thin nature of the connection plates 56, 58 ensure that there is little or no interference with the putter when the rods are removed so that the putter may be ready for playing. It will be understood that the magnets and magnetically attractive material may be replaced with other removable connection means such as double-sided adhesive tape, hook and loop fasteners, inter-engaging tabs, and so on.

The adhesive layer 60 preferably comprises double-sided adhesive tape that permanently attaches the connection plates 56, 58 to the striking face 16. However, the adhesive layer may be formulated to removably attach the connection plates to the striking face. The adhesive layer 60 may alternatively comprise an adhesive coating on the connection plates 56, 58 and/or may be formulated to removably attach the connection plates to the striking face. It will be understood that the adhesive layer 60 may be replaced with other removable connection means such as hook and loop fasteners, inter-engaging tabs, and so on.

As in the previous embodiment, the rods 52, 54 are preferably of solid cylindrical construction with similar dimensions. However, it will be understood that the rods 52, 54 may be hollow and/or of any shape, diameter or cross dimension and/or length.

The alignment device 50 is especially advantageous when it is impractical to form bores in the club head 18 and/or when the head is constructed of a non-magnetic material. Accordingly, the connection plates 56, 58 together with the adhesive layer 60 can be positioned at any position on the striking face 16 and the rods can be removably connected to the plates to ensure that the golf ball is struck at the sweet spot 32 and in the intended direction during training. Prior to actual play, the rods and, if desired, the connection plates and accompanying adhesive layer can be removed so that the same club can be used for both training and playing as previously described.

Referring now to FIGS. 7-10, an alignment device 70 for golf clubs in accordance with a further embodiment of the present invention is illustrated. The alignment device 70 is somewhat similar in construction to the alignment device 50 previously described, with the exception that connection plates 72 and 74 are elongate or oblong in shape so that the guide rods 76 and 78, respectively, can be adjusted along the striking face 16 of the head 18, as shown by phantom line in FIG. 9. In this manner, the guide rods 76, 78 can be adjusted closer together or further apart depending on the skill of the golfer and/or the size of the golf ball. With the exception of their shape, the elongate connection plates 72, 74 are of similar construction to the disk-shaped connection plates 56, 58 previously described. In addition, the elongate connection plates 72, 74 are preferably attached to the striking face 16 of the head 18 in a similar manner as previously described.

Each guide rod 76, 78 is preferably in the form of a hollow tube with a distal end wall 80 and a continuous side wall 82 extending therefrom to form a hollow interior 84 (FIG. 10). It will be understood that the guide rods 76, 78 may be solid and/or of any shape, diameter or cross dimension and/or length. Preferably, each guide rod is constructed of a lightweight, nonmagnetic material such as aluminum or plastic. However, it will be understood that the guide rods may be made of any suitable magnetic or nonmagnetic material.

A magnet 86 is sized and shaped for insertion into the hollow interior 84 at the proximal end 88 of each rod. The magnet 86 is preferably permanently connected to the rod 76, 78 through adhesive bonding, although other connection means can be used, such as press-fitting and so on. Each magnet 86 can be constructed of any magnetic material as long as it is sufficiently strong for holding the guide rod during swinging and striking.

In accordance with a further embodiment of the invention, the magnet 86 may be replaced with a plug constructed of magnetically attractive material and the elongate plates 72, 74 may be replaced with magnetic material to thereby provide mutual attraction between the proximal end of the guide rods and the elongate plates. It will be understood that the rods 76, 78 can alternatively be removably connected to the elongate plates 72, 74 through any well-known removable connection means as previously described.

In accordance with yet a further embodiment of the invention, the guide rods 76, 78 may be telescopic or a set of guide rods of different lengths can be provided, as represented by phantom line in FIGS. 7 and by phantom line and arrows 90 in FIG. 9 so that as a user's skill level increases, a longer pair of guide rods can be used. Thus, the combination of telescopic or longer and shorter guide rods together with the ability to space the rods closer together or further apart provides the golfer with greater training flexibility. It will be understood that telescopic or longer and shorter length guide rods can be used in each of the above-described embodiments.

It will be understood that the term “preferably” as used throughout the specification refers to one or more exemplary embodiments of the invention and therefore is not to be interpreted in any limiting sense. In addition, terms of orientation and/or position as may be used throughout the specification denote relative, rather than absolute orientations and/or positions.

It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It will be understood, therefore, that the present invention is not limited to the particular embodiments disclosed, but also covers modifications within the spirit and scope of the invention as defined by the appended claims.
